specific Embodiment 1

[0045] This embodiment is an embodiment of an information coding structure based on a circumferentially arranged stripe array.

[0046] The information coding structure based on the circumferential array of stripes in this embodiment includes a coding inner layer and an ink outer scraping layer, the ink outer scraping layer is attached to the coding inner layer, and the surface of the coding inner layer is provided with a first disc, a second Second disc and third disc;

[0047] The schematic diagram of the information coding structure based on the circumferentially arranged stripe array before the ink outer scraping layer is scraped off is as follows: figure 1 shown;

[0048] The schematic diagram of the information coding structure based on the circumferentially arranged stripe array after the ink outer scraping layer is scraped off is as follows: figure 2 shown in figure 2 In , use black to represent low grayscale and white to represent high grayscale;

specific Embodiment 2

[0052] This embodiment is an embodiment of an information decoding method based on a circumferentially arranged stripe array.

[0053] The information decoding method based on the circumferentially arranged stripe array of this embodiment is implemented on the information coding structure based on the circumferentially arranged stripe array described in the first specific embodiment, and the method includes the following steps:

[0054] Step a. Scratch off the outer layer of the ink to expose the inner layer of the code;

[0055] Step b, using an image sensor to respectively image the first disk, the second disk and the third disk;

[0056] Step c. Using image processing technology, take the center of the first disk as the center and take any length not exceeding the radius of the first disk as the radius to obtain the corresponding relationship f between the gray scale and the angle on the circumference 1 (l 1 ,α 1 ), take the center of the second disk as the center, and t...

specific Embodiment 3

[0067] This embodiment is an embodiment of an information decoding method based on a circumferentially arranged stripe array.

[0068] The information decoding method based on the circumferentially arranged stripe array of this embodiment, on the basis of the specific embodiment 2, further defines that step k includes the following steps:

[0069] Step k1, encoding the stripes in the first disk, the encoding includes a period code and a gray code;

[0070] Step k2, encoding the stripes in the second disk, the encoding includes a large period code, a small period code and a small grayscale code;

[0071] Step k3, encoding the position line in the third disk, the encoding includes a position code;

[0072] Step k1, step k2 and step k3 are executed synchronously or sequentially in any order;

[0073] The position code, the period code are consistent with the large period code, and the gray scale code is consistent with the small period code;

[0074] Step k4, based on the prin...

Abstract

The invention relates to an information decoding method based on a circumferentially arranged stripe array, and belongs to the technical fields of package transport, encryption and decryption and information security. The method comprises that an external printing-oil scratch-off layer is scratched off, and an internal coding layer is exposed; correspondence between the gray scale and angle of each of first, second and third discs is recorded, rules that strips change with the angle in each of the first and second discs are solved, and rules that an initial line and a position line change with the angle in the third disc are solved; an initial position is searched, and correspondence among strips in the first disc, stripes in the second disc and the position line in the third disc is determined; and according to the correspondence among strips in the first disc, stripes in the second disc and the position line in the third disc, hidden information is identified. According to the method, a manner that personal information is displayed on an express delivery bill directly is changed, and the problem that personal information is leaked via the express delivery bill is solved fundamentally.

Description

technical field [0001] The invention relates to an information decoding method based on a circumferentially arranged stripe array, which belongs to the technical fields of packaging and transportation, encryption and decryption, and information security. Background technique [0002] Online shopping has become an indispensable way of consumption in people's lives, and express delivery has also become an important voucher for transactions between buyers and sellers. At present, since the personal information of both buyers and sellers will be directly displayed on the courier receipt, and the delivery will be carried out according to the information on the courier receipt, the personal information of both buyers and sellers will be completely exposed to the public at all stages of delivery, which will easily cause personal loss of information. According to the survey, more than 70% of personal information is leaked through express delivery documents, which has brought many t...
